The Blue Trapper showing is located on a northeast trending ridge, approximately nine kilometres west of the northern tip of Trapper Lake.

The Blue Trapper occurrence consists of four mineralized showings occurring in an area of up to 400 metres (north-south) by up to 200 metres (east-west). The area is underlain by unspecified volcanic rocks of the Upper Triassic Stuhini Group intruded by quartz dioritic and feldspar porphyry stocks of the Late Cretaceous Windy Table Complex, to the east and north. A granite and alkali feldspar batholith of the Paleocene to Eocene Sloko-Hyder Plutonic Suite intrudes Stuhini volcanics and Laberge Group sedimentary rock to the south and west. Rhyolite and felsic volcanic rock of the Eocene Sloko Group overlie the older rocks in the area.

A rock sample Y642028, taken at the given MINFILE location, assayed 4.6 grams per tonne gold and 4.87 grams per tonne silver; sample Y642124, located 230 metres west-northwest of Y642028, graded 1.1 grams per tonne gold, 30.9 grams per tonne silver and 5.2 per cent copper; and sample Y642258 assayed 3.09 grams per tonne gold, 4.41 grams per tonne silver and 0.08 per cent copper ((Figure 1 (Map B), Press Release, Brixton Metals Corp., Nov.16, 2020).
